  • 1/2 cup EVOO Extra Virgin Olive Oil (count to 8 while slowly pouring)
  • 1/3 cup dry sherry (count to 6 while slowly pouring)
  • 1/4 cup Worcestershire sauce (count to 4 while slowly pouring)
  • Sea salt and coarse black pepper
  • 4 large, firm Portobello mushroom caps (at least 1-inch thick), gills scrapped and caps sliced horizontally into 2 disks
  • 8 slices extra-sharp yellow cheddar cheese
  • 4 brioche rolls, lightly toasted
  • 4 thick slices heirloom tomato
  • A couple handfuls watercress or other spicy greens
  • Salt-and-vinegar potato chips


Serves: 4 servings


Pour EVOO, sherry, Worcestershire and pepper into a dish and mix with your fingers or a whisk. Turn each mushroom disk a few times in the sauce as you add them to the dish; season with sea salt. Let marinate 30-45 minutes, turning occasionally.

Preheat a grill or grill pan over medium-high heat. Grill the mushrooms, turning once, until well marked, 4-6 minutes.

Make 4 stacks in this way: mushroom disk, cheese slice, mushroom and cheese. Place on the grill until the cheese melts, 1 minute. Transfer the stacks to the roll bottoms and top with the tomato slices; season with salt and pepper. Add the greens. Slather the bun tops with the mustard and set in place. Serve with the chips.
